Isahani ishyushye
Irasabwa gushobora kwihanganira kwangirika kwa acide oxyde, sulfate acide sulfate, acide nitric, acide nitric hydrofluoric, acide sulfurike acide sulfate, acide fosifori, aside formike, acide acike nizindi aside.Ikoreshwa cyane mu nganda z’imiti, ibiryo, ubuvuzi, gukora impapuro, peteroli, ingufu za atome n’inganda, ndetse n’ibice bitandukanye by’inyubako, ibikoresho byo mu gikoni, ibikoresho byo ku meza, imodoka n'ibikoresho byo mu rugo.Kugirango harebwe niba imiterere yubukanishi nkimbaraga zumusaruro, imbaraga zingana, kuramba hamwe nubukomezi bwibyuma bitandukanye bidafite ibyuma byujuje ibyangombwa, ibyapa byibyuma bigomba kuvurwa nubushyuhe nka annealing, kuvura igisubizo no kuvura gusaza mbere yo kubyara.
Isahani idafite ibyuma ifite ubuso bworoshye, plastike nyinshi, ubukana nimbaraga za mashini, kandi irwanya kwangirika kwa aside, gaze ya alkaline, igisubizo nibindi bitangazamakuru.Nubwoko bwibyuma byoroshye bitoroshye kubora, ariko ntabwo ari ingese rwose.
Kurwanya kwangirika kwicyuma kitagira umwanda ahanini biterwa nuburinganire bwacyo (chromium, nikel, titanium, silicon, aluminium, nibindi) nuburyo bwimbere.Chromium igira uruhare runini.Chromium ifite imiti myinshi ihamye, irashobora gukora firime ya pasiporo hejuru yicyuma, gutandukanya icyuma hanze, kurinda icyuma icyuma cya okiside kandi ikongera imbaraga zo kwangirika kwicyuma.Filime ya passivation imaze gusenywa, kurwanya ruswa biragabanuka.
Ukurikije uburyo bwo gukora, hari ubwoko bubiri bwo kuzunguruka no gukonjesha, harimo isahani yoroheje ifite uburebure bwa mm 0,5-4 na plaque ifite umubyimba wa mm 4.5-35.
Ukurikije imiterere yimiterere yicyuma, irashobora kugabanywamo ubwoko 5: ubwoko bwa austenite, ubwoko bwa ferrite ya austenite, ubwoko bwa ferrite, ubwoko bwa martensite nubwoko bukomera bwimvura.
Imbaraga nyinshi zidafite icyuma gifite isahani nziza cyane yo kurwanya ruswa, gutembera neza no gukomera kwibice byo gusudira, hamwe no gushiraho kashe yo gusudira hamwe nuburyo bwo kuyikora.By'umwihariko, icyuma kidafite ingese kirimo Si, Mn, P, s, Al na Ni gifite ibikwiye biri munsi ya 0.02% ya C, munsi ya 0.02% ya N, hejuru ya 11% ya Cr na munsi ya 17%, na kuzuza ibisabwa bya 12 ≤ Cr Mo 1.5si ≤ 17, 1 ≤ Ni 30 (cn) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3mo ≥ 16.0, 0.006 ≤ C n ≤ 0.030 bizashyuha kugeza 850 ~ 1250 ℃, hanyuma kuvura ubushyuhe bigakorwa ku gipimo cyo gukonja kirenze 1 ℃ / s.Muri ubu buryo, irashobora guhinduka imbaraga nyinshi zidafite ibyuma bidafite ibyuma bifite martensite irenga 12% kubijwi, imbaraga nyinshi zirenga 730mpa, kurwanya ruswa no gutunganya ibintu, hamwe nubukomere buhebuje bwo gusudira ubushyuhe bwibasiwe na zone.Imikorere ya kashe yibice byasuditswe irashobora kunozwa cyane mugukoresha Mo, B, nibindi.
